Omega HHM-NCV40 Mode D'emploi page 6

on (in standby) will drain the batteries over time. The same
red LED used to indicate detected voltage will flash slowly
and continuously in standby mode to remind you to turn off
the HHM-NCV40. If you still forget to power off the unit, and
fail to confirm that the batteries are charged the next time
you use it, you risk your safety on the results of a test that
the HHM-NCV40 may be unable to perform.
• To avoid electric shock, do not operate the unit without the
battery compartment cover in place.
• Physically separate the multiple lines of 2-phase and
3-phase circuits before testing them.
• Do not use the HHM-NCV40 if it appears to be damaged or
malfunctioning.
• Do not expose the tester to temperatures above 104°F
(40°C), relative humidity greater than 85%, or voltages
higher than 1000V.
• Do not use the HHM-NCV40 to test for the presence of DC
voltage.
• Do not use the unit to test for the presence of AC voltage on
a shielded conductor, behind a wall or conduit, or under
soil.
• Keep your hand behind the finger guard (Fig. 1, Callout 3)
when performing a test. Never touch any conductor with
your hand or skin until you have confirmed that it is not
"hot". Whenever you have reason to believe that a line or
outlet is "hot", measure its voltage with a multimeter or
clamp meter.
